Borucki had a tough year, but in the end he had minor surgery to remove a bone spur and is expected to fully ready for spring. He increased his innings every year from 2016 to 2018 from 135 to 175. He had good command in the minors and showed quite well as a rookie. He had a pretty good spring in 2019 with an eyebrow raising uptick in velocity. Injuries robbed him of the regular season.
We will see how he shows in the spring. Maybe that velocity isn't there. Regardless, I think it's a tad pre-mature to be giving up on Borucki as a starter. It's going to be interesting to see what happens at the end of spring if a couple of these young starters have good springs.
